HONDA CB400F (1974-1976) Specs, Performance & Photos

The Honda CB400F was a slightly modified version of the CB350 model limited only to mechanical changes because Honda devoted much of its resources towards automobile models such as the Honda Civic.

The CB400F featured small modifications compared to the CB350 model, such as an increased bore and a modified cylinder head, which increased the compression ratio, and as a first for Honda, they added a sixth ratio to the transmission.

In terms of appearance, instead of using the looks of the larger Universal Japanese Motorcycle (UJM) CB750, as the CB350F did, the CB400F featured a more cafe racer look with a lower handlebar, rear set footpegs, and a more svelte styling.

The bike was aimed at the sporting segment of the market, but unfortunately, the CB400F lacked in acceleration, unlike its two-stroke competitors, such as the triple from Kawasaki, but made up in other departments with its refinement and the small-displacement engine that ran much smoother, quieter, and was more economical than the two-stroke.

In the performance department, the 1976 Honda CB400F had its heartbeat set by a 408cc four-stroke four-cylinder air-cooled engine that delivered an output power of 37 hp with maximum strength at 8,500 rpm and 33 Nm (24lb-ft) of torque available at 7,500 rpm.
